Can I use Reviva concentrate with genufique in the morning and my visionarie in my nightime routine with my genifique and my renirgie moisturizer ?

That is the ideal routine, and also how I use those same products! Always start with genefique first, then Reviva/Vissionaire, then moisture cream, and let each product fully absorb before applying the next layer for best results.

I am interested in a serum that will repair/hide the look of a fine/medium line near nose and mouth.also between eyebrows. fine/ medium crease

This is the best product that will address the fine line concerns. I was a long time user of the High Resolution Collaser -5x, and was extremely disappointed when Lancôme discontinued it. This product provides very similar results and I am thrilled with it. For the price point, I think this is the best on the market right now. As a Sun Lover and avid year round beach goer in San Diego, at37 years old, I'm often told I look to be in late 20's-early 30's... I thank Lancôme for that. Hope this helps!

How do you use this product?

I use Genefique first, then apply the Renergie Lift Multi-Action Reviva-Concentrate, then my day multi-lift action moisture cream. I let each product fully absorb before I put on the next one. Because of the instant effects, I would only use it for daytime and not waste it on your night routine. For my night routine, I use Genefique, then Vissionaire, then night multi-lift moisture. Vissionaire is designed for long-term results vs this one provides INSTANT firming results. Its the closest product I've used that resembles my greatly missed High Resolution Collaster-5x.
